JOHN H. KNOWLES, OF NEW YORK, N. Y.

EYEGLASS-HOLDER.

SPECIFICATION forming part of Letters Patent No. 436,831, dated September 23, 1890.

Application filed June 28, 1890.

To all whom it may concern:

Be it known that 1, JOHN H. KNOWLES, a citizen of the United States, residing in the city, county, and State of New York, have invented a new and Improved Eyeglass- Holder; of which the following is a specification.

The object of my invention is to produce a holder into which the frame or bow of the eyeglass may readily be inserted and securely held, and yet easily and quickly be removed therefrom when desired. These ends I attain by organizing the holder as a button or clasp provided with means for attaching it to a garment or other article and with a slot or aperture in which the bow or frame of the glass may readily be inserted and automatically secured therein without the use of fastenings, latches, or springs.

The subject-matter claimed is hereinafter In the accompanying drawings, which show devices for carrying out my invention in the best Way now known to me, Figure l represents a face view of my improved holder, showing in dot-ted lines the bow or frame of the eyeglass in the position which it occupies while in the act of beinginserted in the holder and in full lines its position after being inserted therein. Figs. 2, 3, and 4.. respectively represent sections through modified forms of the button or clasp.

The holder is preferably made in the form of a button or clasp A, provided with eyes, holes, or pins a, or other well-known means for attaching it to a garment. A cavity or opening B in the body of the clasp has an entrance-slit 1) formed in one of its walls, preferably of a shape approximately conforming to that of the bow or frame 0 of the eyeglass. The walls or edges of this slit are preferably inelastic, and one edge projects slightly beyond the other on the outside, as

Serial No. 357,114. (No model.)

shown in Figs. 2 and 3, so as to form a slight rib or shoulder 0, against which the bow of the eyeglass may abut to facilitate its insertion into the slot.

The operation will readily be understood from the foregoing description. The clasp being fastened to the garment, the bow is slid along its surface until its curvature conforms to that of the slot, through which it passes to the central opening. The width of the'slit is preferably less than that of the bow or frame. When the glasses are dropped, the frame turns into a position such that its curve differs from that of the slit, so that it cannot escape therefrom Without being turned in the proper position, even were the slit wider than the greatest width of the bow or frame.

It will thus be seen that I secure a cheap, simple, and efficient device for automatically locking and holding the glasses in the position desired.

NVhat I claim as of my own invention is 1. The herein described eyeglassholder, consisting of a body portion having a flat back face adapted to rest against a garment, an internal cavity or opening, and a narrow horizontally-curved lateral slit in front of the back portion and extending from the outside into said cavity.

2. The herein-described eyeglass-holder, consisting of a button or body portion having a straight flat rear portion adapted to rest against a garment, an internal cavity, a narrow slit in the front face extending from the outside into said cavity, and a guide-rib adjacent to said slit.

In testimony whereof I have hereunto subscribed my name.

JOHN H. KNOWLES.
